Computing the ground state of interacting quantum matter is a long-standing challenge,
especially for complex two-dimensional systems. Recent developments have highlighted the …

The Heisenberg triangular-lattice quantum spin liquid and its phase transitions to nearby
magnetic orders have received much theoretical attention, but clear experimental …

Motivated by experimental studies that have found signatures of a quantum spin liquid
phase in organic crystals whose structure is well described by the two-dimensional …

Platelike high-quality NaYbS 2 rhombohedral single crystals with lateral dimensions of a few
mm have been grown and investigated in great detail by bulk methods such as …

We study the spin liquid candidate of the spin-1/2 J 1-J 2 Heisenberg antiferromagnet on the
triangular lattice by means of density matrix renormalization group (DMRG) simulations. By …

At strong repulsion, the triangular-lattice Hubbard model is described by s= 1/2 spins with
nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120° …

Spin systems with frustrated anisotropic interactions are of significant interest due to
possible exotic ground states. We have explored their phase diagram on a nearest-neighbor …

Quantum electrodynamics in 2+ 1 dimensions (QED 3) has been proposed as a critical field
theory describing the low-energy effective theory of a putative algebraic Dirac spin liquid or …

Doubts have been raised on the representation of chiral spin liquids exhibiting topological
order in terms of projected entangled pair states (PEPSs). Here, starting from a simple spin …

Abelian and non-Abelian topological phases exhibiting protected chiral edge modes are
ubiquitous in the realm of the fractional quantum Hall (FQH) effect. Here, we investigate a …
